Provably not all of them.

Zuhair's mistake was trivial, and even he ignored it by using the correct relatoonship further on.

There is that same error again, confusing the properties of surjetion and injection.
A surjection from set A to set B proves Card(A) >= Card(B).
But what WM claims it proved is Card(A) <= Card(B), which is provably false.

Claimed, but not proved, and disprovable anywhere outside Wolkenmuekenheim.

If a word requires use of letters and a path can be identified as an infinite string of digits then even WM ought to be able distinguish between them. As usual, WM is being too sloppy in his terminology to support clear thinking. > > What kind of paths did I use to construct it? > > > What would be a proof is if you manage to define an injection from the > > set of ALL infinite paths of the binary tree to the set of all nodes > > of the binary tree. > > > > If you managed to do that, the next question is: > > > > where is that proof? please show us > > I will it show it to you for all the paths that I used to construct > the above tree and, in addition, for all the paths that you can > identify as beeing missing there. > Promises, promises!
